Rage Across Las Vegas: Phase 1 was the first set of cards for Rage: Tribal War released by Five Rings Publishing Group in 1998. As part of its "Rolling Thunder" program, Five Rings did not release a base set, but rather small card sets in "phases" on a monthly basis. Coming over a year behind schedule, the cards were not stocked by many retailers, which hurt the attempt to revive Rage as a game.
Phase One of the game introduced the Get of Fenris and Wendigo. The accompanying story has the two tribes provoked into a fight at the Hoover Dam after the Get hear rumors that the Wendigo have fallen to the Wyrm. The death of Stillwater Packmother in the fight releases something powerful from the land under the dam, leaving both packs shaken.
